Diabetes Self-Management Education via Telemedicine in the United States Air Force

Diabetes Self-Management Education (DSME) is recommended for patients with a new diagnosis or without prior diabetes education. However, not all Military Treatment Facilities (MTFs) have capacity to provide this resource to patients, which creates a disparity in healthcare. The Diabetes Center of Excellence (DCOE) has an ADA-recognized DSME program and potential to fill this gap through DSME via telemedicine. The Military Interagency Satellite Training (MIST) system, which utilizes satellite technology to broadcast one-way video and two-way audio to distance learners, is available at all MTFs. To test the concept, DSME was broadcast to Randolph Air Force Base (RAFB) from October 2016-October 2017. During this time, 181 patients enrolled in DSME classes; 127 were DCOE patients and 54 were from RAFB. Among data collected were pre/post patient knowledge tests and the validated 17-item Diabetes-related Distress Scale (DDS-17). Knowledge significantly increased from baseline to Class 4. Few patients completed all 4 classes and 6 month follow-up (n=16). Patients had an increase in all DDS-17 domains at the completion of Class 4; however, by 6 months, distress returned to baseline levels. Patient satisfaction surveys were completed at DCOE (n=429) and RAFB (n=227) at each encounter and provider satisfaction surveys were collected from RAFB facilitators. Patients at RAFB reported higher satisfaction (99.1%) than DCOE patients (97.2%). In fact, most measures of satisfaction were higher in RAFB patients than DCOE patients. Moreover, facilitators expressed high satisfaction with DSME via MIST and all facilitators were willing to conduct more classes in this format. Initiation of the DSME Telehealth program presented challenges, especially in technology-related issues and documentation at 6 months. The pilot program allowed the DCOE to gain valuable feedback from our remote site. Technology issues have largely been resolved enabling us to provide an even better experience to our new sites in 2018. Disclosure N. Watson: None. D.G. Acuna: None. J.L. Wardian: None. E.C.

Military Aviation in the Gulf South: A Photographic History by Vincent Caire

Reviewed by: Military Aviation in the Gulf South: A Photographic History by Vincent Caire Heather M. Haley Military Aviation in the Gulf South: A Photographic History. By Vincent Caire. Baton Rouge: Louisiana State University Press, 2016. 128 pp. $39.95. ISBN: 978-0-8071-6411-2. James R. Hansen's 1989 historiographical sketch outlining the state of aviation history drew attention to the lack of engagement with other historical disciplines, including gender, social, and labor histories. Ultimately, Hansen pled with historians to ask intersectional questions that appeal to audiences in "a wider view." By the early-1990s, histories of flight focused almost exclusively on engineering advancements and the military application of flying machines. Hansen noted that, as a result, aviation history had stagnated, "wherein broadly synthetic, contextual, and interdisciplinary studies" would "explore the meaning of a particular field of history in terms of what it means to others."1 In Military Aviation in the Gulf South: A Photographic History Vincent P. Caire responds to Hansen's call for aviation history in the wider view in the most literal sense with his general and celebratory regional history of aviation that stretches across military bases in Texas, Louisiana, Mississippi, Alabama, Georgia, and Florida. Divided chronologically across six chapters—beginning with the Army's 1907 initiative to acquire aircraft for military use through contemporary student flight training practices at Randolph Air Force Base in San Antonio, Texas—Caire's monograph narrows the focus from broader national military aviation history to that of regional. The author [End Page 165] immediately establishes that this history "is not an attempt to present an encyclopedic, all-inclusive chronicle," but he encourages general appreciation and further academic research (xiii). While Hansen sought to influence an adaptive and evolving academic audience, Caire appeals to aviation "buffs" who focus on the intricate details of specific aircraft, notable pilots, and regional military bases. Hansen confirmed the necessity for such monographs like that of Caire's Military Aviation in the Gulf South because they are invaluable sources of raw information, without which "scholars would have a much harder time finding the precise data" that would "put major trends and evolutionary developments into focus."2 Hansen claims that these books typically "resemble the most esoteric treatises on ornithology" as the content on the flying machines themselves limit the narrative strictly to the fascination with aircraft, pilots, and airfields themselves, but this book does not fall into that trap.3 In addition to its value as an encyclopedic reference, Caire's book bleeds into the subdisciplines of science and technology, military history, and transportation. In relation to Alabama history in particular, Military Aviation in the Gulf South is an invaluable resource for beginning researchers seeking basic information on state and local history as it relates to aviation. Caire briefly chronicles the establishment of the Montgomery Air Intermediate Depot with the Army's purchase of Frank D. Kohn's 100-acre cotton plantation located northwest of Montgomery. In November 1922, the War Department renamed the facility Maxwell Field to honor Natchez, Alabama, native Second Lieutenant William C. Maxwell, who died in the Philippines when he purposefully crashed his aircraft into a flagpole to avoid a group of children at play. Ultimately, the Army Air Corps Tactical School (ACTS) selected Maxwell as the center for development in aerial bombing, tactical operations, and aerial support that would maintain an increasing fleet of large aircraft. [End Page 166] Caire addresses cultural and social changes in military aviation with a brief dedication to the first African American primary flight school at Tuskegee Institute and the first African American advanced training programs at Tuskegee Air Field. The establishment of an equitable, albeit segregated, aviation training program for qualified African American pilot candidates was an integral change in military aviation in 1939. Upon induction into the Air Corps, squadron members were selected for fighter or bomber training where members mastered their skills in piloting, navigation, mechanics, and squadron support. Amidst Jim Crow segregation in Alabama, Caire notes, the Tuskegee Airmen initiated military desegregation by proving their capacity "to fulfill such critical responsibilities" in military aviation (52). Vincent Caire's impressive collection and precise incorporation of photographs nicely complements this encyclopedic military...

Achieving Health, Safety, and Performance Improvements Through Enhanced Cost Visibility and Workplace Partnerships

Reduction in the environment, safety, and occupational health (ESOH) component of operational costs requires not only a better understanding of ESOH costs and requirements, but also the formation of effective partnerships between ESOH professionals, financial analysts, and shop workers to identify viable improvements to current practices. This article presents two case studies of efforts to enhance productivity and ESOH in corrosion control facilities at Randolph Air Force Base (AFB), Texas, and Robins AFB, Ga. At each site, activity-based cost models were created to increase the visibility of ESOH-related costs and target improvement opportunities. Analysis of the strip-and-paint processes for the T-38 aircraft at Randolph and the F-15 radome and C-141 aft cowl at Robins revealed that a large proportion of operating costs were tied to ESOH requirements and practices (22 and 39%, respectively).

In each case ESOH professionals teamed with shop personnel to identify potential improvements in personal protective equipment use, waste disposal, tool selection, and work methods. This approach yielded alternatives projected to reduce total shop costs by 5 to 7%. This case study demonstrates how workplaces can identify cost-saving and efficiency-enhancing practices by partnering with ESOH professionals in planning and decision-making activities.

History of Fluorescein Angiography Corrected

<h3>To the Editor.</h3> —In the September 1985 issue of theArchivesan article appeared entitled "Twenty-five Years of Fluorescein Angiography," by Paul A. Blacharski, MD,¹and a letter to the editor by fluorescein angiography pioneer David L. Alvis, MD.²Both are very interesting dissertations. Since both works are historical in nature, I would like to add certain aspects to this history that were omitted in both. In his letter, Dr Alvis mentions that the chairman of the Department of Medicine at Indiana University School of Medicine, Indianapolis, in 1959 was John B. Hickam, MD, and he further states that Dr Hickam had a research grant to study the oxygen saturation of retinal blood vessels by photographic methods. Dr Hickam did indeed have a grant, which was from the US Air Force School of Aviation Medicine, then located at Randolph Air Force Base, Tex. Earlier—in February 1959—Dr Hickam and

Shearing Motion within Scala Media of Cochlear Models

In 1953, Bekesy reported the observation of shearing motion within the cochlear duct, specifically as occurring between the organ of Corti and the tectorial membrane. The direction of this alternating shear motion for any given frequency depended upon the location re the place of maximal transversal displacement of the cochlear duct as a whole. Proximally to the maximum the shear was radially, and distally it was longitudinally directed. This phenomenon was studied with the aid of cochlear models. Not only were Bekesy's original observations confirmed, but the model experiments lend themselves to a simple explanation. Although the displacement of the cochlear duct is commonly represented as a wave pattern with a varying longitudinal curvature only, in reality there are curvatures in both the longitudinal as well as the radial directions because of the fixation of the partition along both of its rims. The shear motion then follows the direction of the dominant curvature in each region which, with reference to the place of maximal transversal displacement, is radially in the proximal region, and longitudinal in the distal region, with a zone of transition at the place of the maximum itself. (Note—directional terms were used here as apply to actual cochleae.) [This work was supported in part by the U. S.

Space medical research.

SPACE medicine, today, can look back upon a ten-year history. It came officially into being in February, 1949, with the foundation of a special department of space medicine at the School of Aviation Medicine, Randolph Air Force Base, Texas, by its commandant, Major General Harry G. Armstrong. At about the same time preparations for animal experiments in rockets were started at the Aero Medical Laboratory, Wright–Patterson Air Force Base, Dayton, Ohio. Facilities available for these grand-scale experiments, at Holloman Air Force Base, New Mexico, later became an independent institution under the name of Aero Medical Field Laboratory.At that time . . .

Day-to-Day Stability of the Auditory Threshold in Noise-Exposed and Non-Noise-Exposed Air Force Personnel

Individual pure-tone threshold tests were manually administered to three groups of men: Group I—27 flight-line personnel who were exposed to job noise during the test week; Group II—24 flight-line personnel who were not exposed to job noise during the test week; Group III—52 non-flight-line men. A modified psychophysical method of limits was used, and the intensity of the test tones was varied in 2-db steps. Thresholds for 250 cps through 6000 cps were established. Each man was tested daily, Monday through Friday, at approximately the same time each morning. The noise-exposed men were tested prior to daily noise exposure. Results are summarized as follows. (1) Most mean thresholds in the three groups on Tuesday through Friday were better than on Monday. The largest mean improvement in sensitivity was 2.2 db (Group II at 250 cps on Thursday), and the largest mean reduction in sensitivity was 1.7 db (Group I at 6000 cps on Friday). Improvement in measured auditory sensitivity during the test week is interpreted as indicative of a learning effect. (2) Intra-subject variability in thresholds at 4000 cps and at 6000 cps was not related to threshold sensitivity. (3) No cumulative short-term temporary threshold shift occurred in the noise-exposed men during the five-day test period.

Beats in Cochlear Models

Particle motion within the fluids of cochlear models occurs in elliptical orbits which are essentially Lissajou figures caused by interaction between the (forced) stapedial motion and the (induced) motion of the cochlear partition [J. Acoust. Soc. Am. 29, 558 (1957)]. In response to beats these orbits were found to wax and wane synchronously with the beat frequency. However, the alternating waxing and waning was not symmetrically centered about the orbital midpoints. In scala vestibuli, the orbits invariably expanded farther in the apical than in the fenestral direction. In scala tympani, the directions were reversed. Thus a partial rectification occurred within the cochlear fluids which, being synchronized with the beat rate, was of opposite direction in both perilymphatic scalae. This manifestation of energy at the beat frequency had to be due to some nonlinear property of the model, since no energy occurs at this frequency in linear systems. The nonlinear property was finally identified as the stiffness gradient of the cochlear partition. The resulting beat amplitude (re particle amplitude of a given set of primaries) was directly related to the steepness of the stiffness gradient. Furthermore, the beat amplitude reflected upon the shape of the gradient at various locations along the partition when beats (of a constant rate) were produced by different sets of primaries.

Acute Clinical Effects of Penetrating Radiation

Localization of Aural Harmonics along the Basilar Membrane of Guinea Pigs

Harmonic distortion has been shown to originate hydrodynamically in cochlear models; its essential manifestation being Békésy's “eddies” and their sequelae. One of the major postulates derived from this study was that the distortion be resolved along the cochlear partition in accordance with the place principle of frequency localization. Experiments on guinea pigs were conducted in an effort to support this latter postulate. A method of recording cochlear microphonics by means of differential electrodes was chosen. This method had been previously used by Tasaki, Davis, and Legouix for mapping amplitude and phase alteration along the basilar membrane. The results of the present study indicate (1) that distortion within the cochlea occurs at a lower intensity level than it does in the middle ear (confirming results of earlier investigators), and (2) that each newly created harmonic forms a traveling-wave pattern of its own along the basilar membrane in accordance with the place principle. These results support the hydrodynamic hypothesis of the origin of intracochlear distortion.

Localization of Aural Harmonics Along the Basilar Membrane of Guinea Pigs

Harmonic distortion resulting from cochlear overload is caused by Békésy's “eddies,” according to experiments on cochlear models [J. Acoust. Soc. Am. 29, 1249 (1957)]. This hydrodynamical distortion (1) does not affect the mechanical response of the round window and (2) is resolved along the cochlear partition in accordance with the place principle of frequency localization. Wever and Lawrence, however, had concluded that intra-cochlear distortion occurs at the haircell level [Physiol. Acoustics (Princeton, 1954)]. In this latter case resolution should not be in accordance with the place principle. Tasaki et al. [J. Acoust. Soc. Am. 24, 502 (1952)] have demonstrated (by use of differentiating electrodes inserted at several points along the cochlea) phase variations of cochlear microphonics in accordance with the traveling wave concept of Békésy. This latter method was adopted for purpose of the present study. Two alternatives were visualized. The haircell hypothesis would be supported if the complex wave forms resulting from cochlear overload would look identical (except for differences in amplitude) when being picked up at various points along the basilar membrane. The hydrodynamical hypothesis would be supported if wave forms at various pickup points would differ in (a) amplitude, (b) harmonic content, and/or (c) phase relation among harmonics. The results to be presented are in favor of the second alternative. [This research was supported by the United States Air Force under contract number AF 41 (657)-148, monitored by the School of Aviation Medicine, USAF, Randolph Air Force Base, Texas.]

Harmonic Distortion in Cochlear Models

The envelope over the train of waves traveling along the cochlear partition is asymmetrical: the distal slope being steeper than the proximal one [G. von Békésy, J. Acoust. Soc. Am. 19, 452 (1947)]. In experiments on models, this asymmetry was seen to increase with intensity. Since the mean revolving velocity of Békésy's “eddies” also varies with intensity, artificial “eddies” were introduced into the model while the intensity remained constant. Thereby the asymmetry of the envelope was also increased. Propulsion of the “perilymphatic” fluids by the “eddies” converts particle motion (ordinarily in closed orbits) [Juergen Tonndorf, J. Acoust. Soc. Am. 5, 558 (1957)] into cycloids. As the eddies accelerate along the partition (see the paper by Tonndorf), the cycloids expand with distance, its velocity attaining a sawtooth-like pattern. The asymmetry of the envelope can be explained satisfactorily by the combined effect upon the partition of the distorted cycloids in both “perilymphatic scalae.” However, the same theoretical considerations lead to asymmetry of the displacement pattern of the partition and to an effect similar to peak clipping, both of which increase with distance. This distorted displacement pattern in the distal region of the partition in turn affects particle motion in the adjacent fluids, whence the distortion is propagated proximally by the eddies to be resolved in the usual way (see the paper by Tonndorf) along the cochlear partition. [This research was supported in whole or in part by the U. S. Air Force, under Contract No. AF-41 (657)148, monitored by the School of Aviation Medicine, UASF, Randolph Air Force Base, Texas.]

Hearing Acuity of Air Force Flight-Line Personnel: a Preliminary Report

Pure-tone audiometric tests and job-, noise-, and medical-history questionnaires were administered to 599 Bergstrom Air Force Base flight-line personnel. Hearing loss at 4000 cps, total hours of exposure to high-level on-the-job noise, and age were analyzed to determine the inter-relationships between these three variables. At 4000 cps (worse ear) the observed mean hearing losses in eight Air Force Specialty groups ranged from 14.8 db to 20.6 db re audiometer zero. No statistically significant differences were found between group hearing-loss means when adjustment was made for differences in age and noise exposure. The interrelationships between hearing loss, age, and noise exposure were similar from one Air Force Specialty group to another. Hearing loss at 4000 cps and age were positively correlated. Age and noise exposure were positively correlated with hearing loss and noise exposure. The partial correlation coefficient between hearing loss and age differed significantly from zero. However, the partial correlation coefficient between hearing loss at 4000 cps and noise exposure was not statistically significant. These results are evidence that an extremely complex relationship exists between noise-induced hearing loss and age plus total exposure to high-level intermittent continuous noise.
